So the pad is now usable via the Brook PS3 to PS4 converter update.
Everything is great excluding one thing...currently, at least with the black Saturn pad, the input for L3 does not function properly currently. We may see an update really soon to fix this.
Otherwise, the controller works very well with MK11. There is a slight relearning process if you are used to 4 shoulder buttons, and the controller's layout uses Z and C as R1 and R2 respectively, while L and R are for L1 and L2.
